Strategies for building large systems that can be easily adapted for new situations with only minor programming modifications. Time pressures encourage programmers to write code that works well for a narrow purpose, with no room to grow. But the best systems are evolvable; they can be adapted for new situations by adding code, rather than changing the existing code. The authors describe techniques they have found effective--over their combined 100-plus years of programming experience--that will help programmers avoid programming themselves into corners. The authors explore ways to enhance flexibility by: Organizing systems using combinators to compose mix-and-match parts, ranging from small functions to whole arithmetics, with standardized interfaces Augmenting data with independent annotation layers, such as units of measurement or provenance Combining independent pieces of partial information using unification or propagation Separating control structure from problem domain with domain models, rule systems and pattern matching, propagation, and dependency-directed backtracking Extending the programming language, using dynamically extensible evaluators

A guide to using the power of design flexibility to improve the performance of complex technological projects, for designers, managers, users, and analysts. Project teams can improve results by recognizing that the future is inevitably uncertain and that by creating flexible designs they can adapt to eventualities. This approach enables them to take advantage of new opportunities and avoid harmful losses. Designers of complex, long-lasting projects—such as communication networks, power plants, or hospitals—must learn to abandon fixed specifications and narrow forecasts. They need to avoid the “flaw of averages,” the conceptual pitfall that traps so many designs in underperformance. Failure to allow for changing circumstances risks leaving significant value untapped. This book is a guide for creating and implementing value-enhancing flexibility in design. It will be an essential resource for all participants in the development and operation of technological systems: designers, managers, financial analysts, investors, regulators, and academics. The book provides a high-level overview of why flexibility in design is needed to deliver significantly increased value. It describes in detail methods to identify, select, and implement useful flexibility. The book is unique in that it explicitly recognizes that future outcomes are uncertain. It thus presents forecasting, analysis, and evaluation tools especially suited to this reality. Appendixes provide expanded explanations of concepts and analytic tools.

Design for flexibility requires anticipation, preparation, creativity and experience. Future highly digital sociotechnical systems should contrast with those stemming from technology-centered engineering that produces objects and machines with the immensely codified and rigid practices we know today. Most of the time, current technologies are designed and developed for normal situations, leaving users to manage abnormal and emergency situations themselves, sometimes under unforeseen, extreme and/or dangerous conditions. Putting humans at the center of the design of flexible sociotechnical systems means visualizing possible futures, modeling them, simulating them and leading them down the right paths. This book is for the engineering designers, who seek to better understand the roles of humans and organizations developing complex life-critical systems. It is also for those who train future designers who will have to take into account the well-being, safety, sustainability and efficiency of the actors of future sociotechnical systems. It is about an emergent discipline, human systems integration (HSI). The aim of the flexibility challenge is to put the artificial at the service of the natural, and not the other way around. The author, an aerospace engineering designer, has worked for 40 years in the field of human-centered design (HCD) of complex systems, discovering repeatedly that automation leads to rigidity, especially when things go wrong. It is urgent we had a new paradigm where flexibility is a major asset in human systems integration. HCD is seen here as the combination of practices and technologies to come.

"This book is an attempt to better formalize a systemic approach to Human-Systems Integration (HSI). Good HSI is a matter of maturity... it takes time to mature. It takes time for a human being to become autonomous, and then mature! HSI is a matter of human-machine teaming, where human-machine cooperation and coordination are crucial. We cannot think engineering design without considering people and organizations that go with it. We also cannot think new technology, new organizations and new jobs without considering change management. More specifically, this book is a follow-up of previous contributions in Human-Centered Design and practice in the development of virtual prototypes that requires progressive operational tangibility toward HSI. The book discusses flexibility in design and operations, tangibility of software-intensive systems, virtual human-centered design, increasingly-autonomous complex systems, Human-Factors and Ergonomics of sociotechnical systems, systems integration, and changed management in digital organizations. The book will be of interest to industry, academia, those involved with systems engineering, human factors and the broader public"--

Flexible housing is housing that can adjust to changing needs and patterns, both social and technological. This book argues that flexible housing has the potential to make a key contribution to more adaptable and therefore more sustainable buildings, showing how it has clear social and economic benefits. As the first comprehensive overview of this important subject, the book examines the past, present and future of flexible housing, collecting together over 160 international examples of the genre as a major point of reference. Combining history, theory and design, the book both makes the case for flexible housing and also shows the various ways by which it has been, and can be, achieved. Specially commissioned plans, printed to scale, together with over 200 illustrations and diagrams allow direct visual comparisons to be easily made. The book ends with an accessible guide to how flexible housing might be designed and constructed; it is thus both a major historical reference and an immediately useful manual. It will be of immense value to housing architects and designers, housing managers and developers, and to students of architecture, construction and housing.

Flexible manufacturing systems are complex production systems with considerable high investment costs. This book intends to show the reader how the design of such a system can be optimized. Thereby it addresses the academic world in management science and industrial engineering as well as system planners in industry. First the design problems are analysed in detail and a planning concept is presented. Afterwards possible tools for the design process are described, as there are: mathematical programming, queueing networks, computer simulation, perturbation analysis, petri nets, group technology, and knowledge based systems. The major part of the book, however, concerns the description of existing optimization models based on mathematical programming. Each model is explained and discussed in detail and for new models, developed by the author, numerical examples are given. Finally some distinct guidelines are presented which help the system planners to select the appropriate model for their planning problems.

Competition among companies that produce complex or large product portfolios has created a need to use modularity strategies not only to flexibly manage technical complexity in a cost-effective manner but also to produce visually appealing products. This research aims to understand how the visual appearance of products is affected by modular product development strategies and creates coherent product brands. Thus, this study examines the intersection of design aesthetics, product portfolio management, product brand management, and design management. Specifically, this study aims to understand how such strategies constrain and generate possibilities when the industrial design process concerns itself with visual appearance. The main research approach has been qualitative multi-case methodology (Miles et al, 2014; Eisenhardt, 1989) and design theory building (Chakrabarti and Blessing, 2016) that collects data through interviews, experimentation, and theoretical studies based on findings in the literature. Sixteen face-to-face interviews were conducted with design vice presidents, senior designers, and senior design engineers at five Swedish manufacturers from the automotive, MedTech, consumer goods, commercial vehicles, and materials handling industries. This approach has resulted in the description of three theoretical models and a design method, product gist, for investigating prototypicality in a product category. Aesthetic flexibility reflects the requirement that under certain circumstances an industrial designer has to plan for future (as yet unknown) changes in a design. Each of the three theoretical models has a different focus: one model describes three ways manufacturing companies organise a strategic in-house design function; one model describes how design decisions are made on a general level through an intuitive and knowledge-based judgment process; and one model describes the strategies a manager needs to consider when developing an existing product portfolio and how the strategies influence industrial design practice. Understanding visual flexibility serves as a starting point for further investigations of how development strategies affect visual product design. This understanding provides industrial designers insight into how they can develop product systems that share design components across product lines to promote brand identity. The findings of this work illustrate and explain a complex and multi-facetted design phenomenon that many designers manage more or less intuitively today; therefore, this study advances the understanding of the field for academics, teachers, and professional designers.
